E-waste toxins polluting Ghana

The circular economy has infiltrated the board rooms of Australian and New Zealand water utilities, according to a new report. Now to put these ideas into action. Bricks made from biosolids (bacteria and urea found in human urine) could play a role in circular water system in Australia that avoids heavy metals, microplastics and other pollutants ending up in our waterways.  According to a recent Water Services Association of Australia report on water management in a circular economy, organic building materials like this tick several boxes for a circular economy as they can be returned to the biosphere at the end of their useful life.  The “Bio-Bricks” invention is just one of many interesting technologies identified in the report. Another valuable material that could be extracted from urban waterways for circular economy purposes, WSAA chief executive Adam Lovell says, is hydrogen.
